To @ZZ u'tom muy concern:

'2e it known that I, JEAN Vieron Gann, a citizen of the Republic of France, residing` at Iaris, in France, have invented a new and use `fnl Machine for Boring Bruslrlcdies, (pat ented in England, No. 13,448, dated October 2l, 1886, scaled August 23, lSST,`) of which the following` is a specification.

The aim of my invention is to provide an apparatus by which bruslrbodies may be properly supported and quickly adjusted during the operations of boring,` the tutt-receiving holes therein, or during,1 the operation of inserting,` the tufts into said holes, and is intended, more particularly, for use in the manufacture of brushes having cylindrical bodies with the tufts arranged radially therein, although it is to some extent applicable in the manufacture of brushes having` bodies of dat or other forms.

In the accompanying,r drawings I have illustrated my machine as adapted and applied to the manufacture of cylindrical. brushes.

Figure l represents a side elevation of the machine, certain of the minor portions beingreprcscnted in section. Fig. 2 is an edge view of the machine with minor portions in section. Fig. 3 is atop plan view of the lower portions ofthe apparatus. Fig. d is a longitudinal central section through the telescopic support 'for the bruslrbody ou the line a: of Fig. l. Fig. 5 is a horizontal sect-ion ou the line fr m' of Figs. r2 and Li.

My machine consists, essentially, of a pendent telescopic spindle on which the brushbody is supported, combined with means for adj listing said spindle vertically, and with guides or supports which cooperate with the brush-body to hold the same in proper relation to the boring or tutt-inserting devices.

Vhile I have for elearness of explanation thus illustrated an ordinary form of boring machine in connection with my apparatus, it is to be understood that the apparatus may be used in connection with boring` or tuft-insert ing mechanisms of any approved form, these matters being foreign to the present invention.

Referring to the drawings, A represents a horizontal guide-plate fixed rigidly in an overhead position on any suitable support; B, a castdrou frame adapted to engage the edges of said plate and to slide horizontal ly thereon under the inliuenceof an adjustingscrew, C, one end of which is threaded into the movable frame, while the other is swiveled in the guidcplate. g1'

The screw is provided with a ooved pulley, c', supporting an endless belt,

c, which extends downward within convenient reach of the attendant, its lower end being` provided with a weighted pulley to keep it in position.

G represents a horizontal ring connected by horizontal pivots f to arms F, forming parts of the frame B. This ring; is also connected by horizontal pivots f at right angles to those above mentioned, to the upper end of a tube,

, the two series of pivots and the ring constituting an ordinary universal joint of the form known as a gimloal-joint,77 by which the tube H is sustained and its lower end per mitted to swing freely in all directions. The tube H contains a second tube, I, arranged to slide therein, and this inner tube in turn iu closes a rod, J, the lower end of which is projected and exposed to receive and sustain the brush-body.

rlhe two tubes and the rod constitute jointlyan extensible or telescopic spindie. rilhe upper end of the rod J is connected by an ordinary swivel-joint, J', to the lower end of asuspending wire or chain, D', attached journaled in the frame B.

and arranged to Wind upon a drum, D, The drum D 1s provided on one side with a series of wormteeth, D2, which engage a worm, E, on a herr zontal shaft, E', mounted in the frame B, so

at the rotation ofthe worin turning the drum will cause the wire to raise or lower the brushsupporting rod J, as occasion may require. The worm serves when at rest as astop or detent to hold the drum against rotation and maintain the lower end ol' the'spindle at the height to which it may be adjusted. The means for turning the worm and controlling its movement, so as to raise or lower the spindie definite and equal distances, will be hereinafter described.

The cylindrical brush-body S, which it is the object of my machine to sustain, is provided with a central opening from end to end, so that it may be slipped endwise upon the rod In order to hold the body thus applied in ICO position, the'rod is providedwith two conical sleeves, J 2 and J 3, arranged to enter the ends ofthe body, as shown in Figs. l and 2. The cones admit of the bruslrbody being revolved around the rod or spindle to present its di t'fern ent sides to the boring-tool, hereinafter dc- Ihe lower sleeve may be held in position by apin andthe uppersleevc by gravity, or fastening devices oil anysuitable character, such as will suggest themselves to the intelli gent mechanic, maybe used to secure the cones in place.

The foregoing parts constitutej ointly a mechanism adapted to sustain the brush-bod y in an upright position to move it horizontally and vertically', and tc admitofits being rotated or moved laterally at will.

In Fig. l R represents an ordinary boringmachine with a horizontal spindle provided with a boring or drilling tool, r, to act upon the brush-body while it is suspended in position. This boring apparatus is located at one side of the position occupied by the bruslr body, so that the axis of its spindle occupies a radial or approximately' .radial position with reference to the center of the brush-body, or substantially so.

In order to properly guide the body as it is presented to the boring-tool, I iix upon a stationary support, T, a horizontal body, K, the forward end of which is provided with a rest, N, adapted to bear against the surface of the bruslrbody. The bar K slides horizontally through guides L L, and is provided with a threaded arm or screw, M, which passes through the guide L and is secured by adj listing-nuts, as shown in Figs. I and 3. By turning these nuts the bar K may be moved forward and backward as required. rIhe rest N has a threaded shank extending transversely through the bar K, and provided with a clamping-arm, as shown, so that its operative end may be adjusted transversely of the bar K, as the varying diameter of the brush-bodies may demand. The body supported by the rod J and guided by the rest N is further controlled by the hands of the operator,who forces it against the boring-tool until a hole of proper depth is formed, after which he draws it from the tool, gives it a partial rotation in a horizontal direction, and again presents it to the tool for the formation of the next hole, and so on repeatedly. The body is preferably provided, previous to its introduction to the apparatus, with vertical lines properly placed to indicate the horizontal distance between thelioles, and thus guide the operator in its application to the boring-tool. After the completion of a row of holes around the circumference of the body itis then to be raised or lowered a proper distance to admit of the next row or line being formedu In order that the operator may thus adjust the body vertically and to the ex'- act position required, I mount on the wormshaft E a sprocket-wheel, e, ltrom4 which an endless chain,e, is extended downward around a sprocket-wheel, o', turning on a pivot-bolt,

madjustably secured to a vertically-slotted arm, 0, on the under side of the bar` By moving this chain the operator is enabled to operate the worm-wheel, and through the intermediate parts to raise 'or lower the rod J and the bruslrbody, as before explained. To an arm on the bar K, I secure an upright screw-rod, I, lying parallel with one side of i the chain, and on this rod I mount a looselysliding sleeve or hand-piece, Q., provided with a rib'or'feather entering longitudinal slot in the rod, as shown in Fig. l, whereby it is prevented from turning round the same. I providethis sleeve in one side with a pivoted finger, q, urged outward by a spring, q', and fashioned at its free end to engage the links of the chain. O11 the upper end of the rod I mount an adjustable nut, j), to limit the up ward movement ofthe sleeve. When .it is required to adj ust the brush-body vertically, the operator moves the sleeve Q upward until its movement is arrestedby the nut p, where` upon he presses the finger q inward until it engages the chain, and, holding it in engagement, moves it downward to the lower'end of the rod, thereby operating the chain E and adjusting the body, as before explained. The nut p, acting as a stop, secures equal movements of the chain and equal adjustments of the brush-body. By turning the nntp downward and diminishing the movement of the chain the holes in the brush-body will be brought :nearer together, and vice versa.

The horizontal movement of the suspending devices upon the slide A is advantageous in that it permits the spindle to hang normally at any required distance from the end of the boring-tool. In this manner the apparatus may be adj usted to receive and hold in the required relation to the boring-tool brush-bodies of dit ferent diameters, and also of the bodies being suspended in such manner that the holes'may be bored at any required angle tothe axisofthe body.

Having thus described my invention, what I claim isl. In a mechanism for supporting brushbodies while being bored,the extensible pendulous spindle, a suspending-wire connected to the lower member' of said spindle, the Windn ing-drum for said wire, and the operating mechanism for said drum, substantially as described, whereby the lower-end of the spindle is permitted to swing freely in a lateral direction and rendered capable of vertical adjustment at will.,

2. In combination with a horizontal guide, the sliding frame B, the extensible spindle suspended therefrom bya universal joint, the winding-drum, the wire or chain suspending the lower member of the spindle from said drum, and mechanism, substantially as de-` scribed, for turning the drum, whereby a brush-body may be supported, adj usted horizontally, raised and lowered, and permitted to swing laterally.

3. In combination with the extensible spin- IOO IIO

dle, the suspending-Wire, the winding-drum, the Worm-gear for turning said drum, the endless chain and its supporting-links for open ating the worm, the sleeve Q, for moving said chain, and an adjustable stud to limit the movement of the sleeve.

et. In a machine for boring brush bodies,and in combination with an overhead guide, the frame movable horizont-all y thereon,the frameadjustng devices, and the pendent cord or belt for moving the same, and the pendent spindle to support the brush-body.

5. In combination with the rod J, the teleseopie rods II and I, the supporting-frame B, andthe gimbal-joint connecting the tube H with said frame, whereby the cylindrical brushbody may be held and guided,subject to longi tndinal rotary and lateral movements.

G.
